- v. Present participle of dewet.
Sorry, no etymologies found.
Using model polymers with well understood crystallization behavior, the team discovered that a few degrees 'variation in temperature controls whether crystallization or dewetting will dominate the hardening process.
The team has determined that temperature can play a decisive role in determining which of two competing processes-called crystallization and dewetting-will "take the lead" when a semicrystalline polymer film hardens, thereby granting qualitatively different properties to the finished film.
If crystallization and dewetting occur simultaneously, they can couple to create imperfections that can be a nuisance for applications that rely on film uniformity, such as organic solar cells.
Competition between crystallization and dewetting fronts in this polymer films.
They also found that when two growing crystals expand and collide, the stress created where they contact each other can cause dewetting-but if the angle between the two expansion fronts is small enough, then this localized dewetting might be averted.
